Welcome, I too am a relative newbie (2yrs) having started after being passed my grandads accumulation one Xmas, nothing valuable but full of history and my avatar pic was the first coin I ID'd. I started thinking my interest was George III as I liked the Sharpe films. Even though there's some great numismatic interest in this period, my interests never really developed, I don't know why. I have since moved into type collecting milled half-crowns and working my way through the various mints and moneyers of Henry III silver pennies which can be got in brilliant condition at relatively cheap prices!
From my own experience I'd advise not to get too "het up" in initially defining what type of collector you are and just buy what you like the look of. And please, for goodness sake, do not collect milled pennies! Variety is the spice of life!
